1. A method comprising:
- receiving, by a wearable device, motion information from a motion sensor of the wearable device;
determining, by the wearable device using the motion information, that a vehicle is turning, the determining comprising;
determining an angular velocity of the wearable device;
estimating the angular velocity of the wearable device attributable to the vehicle; and
determining that the vehicle is turning in response to the estimated angular velocity exceeding a threshold value of angular velocity;
estimating a direction of gravity relative to the wearable device based on the motion information from the wearable device;
determining a turning axis of the vehicle based on the estimated direction of gravity and the motion information from the wearable device; and
in response to determining that the vehicle is turning, determining, by the wearable device using the motion information, that a user of the wearable device is controlling the vehicle by subtracting angular velocity of the vehicle due to the turning of the vehicle about the turning axis from the determined angular velocity of the wearable device and determining that a difference of the subtracting is greater than zero.
